I v e,416,7s 2 a I 1 ADJUSTABLE v-BLooK Paul Valish, Waterbury, Conn.Application May 12, nit-seal; Noi'5e5'3s3 The invention relates to ashaft support or rest, and more especially to an adjustable, v-block formachinists use.

The primary object of the invention is the provision of support, rest orblock of this character, wherein the same can be keyed to a machinetable, so that a machinist can accurately line a shaft for the truingthereof, without the use of shims or other like parts, and such support,rest or block is susceptible of easy-and quick adjustment for the propersetting of the shaft.

Another object of the invention is the provision of a support, rest orblock of this character, wherein the construction thereof is unique andnovel, it being readily and easily. applied and removed to and'f'rom thework, and is applicable to varying diameters of shafts for the truingoperation thereon.

A further object of the invention is the provision of a support, rest orblock of this character, which is simple in its construction, thoroughlyreliable and eflicient in purpose, strong, durable, compact, serviceablefor various kind of work, and inexpensive to manufacture and install.

With these and other objects in view the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawings, which show the preferred embodiment of the invention andpointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is an elevation of the device constructed in accordance withthe invention.

Figure 2 is a top plan view thereof.

Figure 3 is a sectional view on the line 3-3 of Figure 1, looking in thedirection of the arrows.

Figure 4 is a sectional view on the line 4-4 of Figure 1, looking in thedirection of the arrows.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings in detail A designates generally the support,rest or block constructed in accordance with the invention andhereinafter set forth in detail.

The support, block or rest A comprises a solid base I 0, having at thelower flat faced portion centrally thereof in a longitudinal direction akey II for fitting in the slot in a machine table (not shown). Upon thisbase I is built a boxing including the vertical side walls l2, which areof uniform height with respect to each other and. meet the upper face ofthe said base III, while at right angles to the said side walls are endwalls 3 Claims. (01. co -59$ l3, these being united to the side wallsinany suitable manner, and have their lower edges elevated from theupper face ofthe base. The upper edge of the'end'walls' I have provided;therein horizontally aligned V-shapednotches l4 opening upwardlytherefrom. r

The inner surface of the side walls l2 'ar e beveled as at I5 so as toconverge in one direction toward each other, and between the side andend walls l2 and I3 is createda well I6 in which is loosely fitted acentering lifting jack including a turn screw l1 threaded centrally inan adjustable, bearing head l8, which is V-notched in its upper face foraccommodating upwardly divergent rest or contact plates I9, these beingV-set corresponding to the notch or crotch 20in the. saidhead 18 for thesupport or resting of a shaft (not shown) to be trucd in a truingmachine which is also not shown in the drawings.

The meeting faces of the head l8 conforms to the inner surfaces of theside and end walls l2 and I 3 of the well l6 created by the boxing. Thescrew I! has its lower spindle end 2| displaceably fitting a recess 22in the base I 0 provided-therefor. This recess 22 allows for thecentering of the head I8 when supporting a piece; of work, as forexample a shaft, in the truing. thereof.

Next to the spindle end 2| .of the screw I1 is integrally formed thereona peripherally socketed turning rim 23 so that a pin or bar can be se-,lectively engaged with a socket therein for the easy turning of thescrew in the adjustment of the head l8 to raise and lower the same forthe lifting or lowering of the work held thereby.

Tapped centrally in the end walls It .are horizontally arranged setscrews 24, wrench engageable, and one of these screws 24 plays against agripping plate 25 countersunk in the end wall l3 next thereto, and thisplate 25 has contact with the head l8, the plate 25 being held fromdropping or displacement by retaining pins 26 from its seat in avertical direction.

The rim 23 is accessible through openings 21 between the base [0 and theend walls I3, so that the screw I! can be regulated in the adjustment ofthe head l8, and such access is had with respect to either end of thesupport, rest or block.

Many times in a machine shop shafts having a number of unequal diametersor dimensions have to be machined. The machinist has toset the shaft ina V-block or blocks and line up the shaft by placing shims under one orthe other end of such shaft.

The shims may be one-fourth or one-half inch scrap steel, tin or merepaper, a very flimsy but common method; used in some of the best shops,so by using the device herein described, this method is entirelyeliminated.

The device is always looked in place centrally,

and it can be keyed in the machine table slot with which the said deviceis used.

The sides and ends l2 and I3 are preferably united together by fasteners28, while the plates are secured in position with respect to each otherby fasteners 29, respectively.

From the foregoing itis believedthat the con:- struction and manner ofuseof the device will be clearly understood and therefore a moreextended. explanation has been omitted for the salient v r v Changes,variations and modificationsimay'be" brevity.
